Background Art

[0002] With the continuous improvement of product quality, more and more companies (such as automobile manufacturers) have increasingly stringent requirements for the thickness of stainless steel strip (stainless steel coil). If the thickness of the stainless steel is less than the lower limit, the product produced will not meet the standard. If the thickness exceeds the upper limit, not only will the raw material cost increase, but the mold may be damaged during stamping. Therefore, the requirements for the three-point difference of stainless steel strip in the width direction are becoming increasingly strict. However, during the current coil rolling process, the hot rolling furnace coil mill has only one stand, and the steel coil needs to be rolled back and forth multiple times with the same roller. Due to the large three-point difference of the steel coil, it is very easy to cause severe wear of the roller in the same position.

[0066] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0067] Implementation Method 1

[0068] The present invention provides a roller debugging method, which uses a wear-resistant roller to replace the original roller. The wear resistance of the wear-resistant roller is better than the wear resistance of the original roller. The wear resistance of the roller described in the present invention can be one or more properties of the roller's hardness, toughness, and ability to form an oxide film on the surface. It is necessary to ensure that after rolling the steel strip for the same time or rolling the steel strip of the same length, the wear of the wear-resistant roller is less than the wear of the original roller.

[0069] like Figure 1 As shown,

[0070] The roll debugging method includes:

[0071] Step S1: presetting a standard parameter range of the wear-resistant roller;

[0072] Further, such as Figure 2 As shown, step S1 includes:

[0073] Step S101: Obtain the parameter values ​​of the original roller; wherein the parameter values ​​of the original roller can be directly obtained by detecting the original roller, such as: the temperature value that the original roller can reach after rolling the steel strip for a preset time or the original roller rolling a preset length of steel strip, and / or the wear amount of the original roller, which can be obtained by collecting and recording data during the daily rolling process.

[0074] Step S102: Determine a standard parameter range for the wear-resistant roller based on the parameter values ​​of the original roller. The standard parameter range for the wear-resistant roller can be preset based on the obtained parameter values ​​of the original roller. This range includes the temperature range that the original roller can reach after rolling the steel strip for a preset time or a preset length of steel strip, and / or the wear range of the original roller. Within this range, the wear-resistant roller is considered to meet the parameter standards and can meet the rolling requirements for the steel strip. It should be noted that the standard parameter range for the wear-resistant roller can be set and adjusted according to different rolling requirements for the steel strip, so as to meet the rolling requirements for the steel strip.

[0075] Step S2: obtaining actual parameter values ​​of the wear-resistant roller;

[0076] Step S3: If the actual parameter value exceeds the standard parameter range, the actual parameter of the wear-resistant roller is adjusted;

[0077] Step S4: Repeat the above steps S2 to S3 until the actual parameter value obtained is within the standard parameter range.

[0078] The present invention uses a wear-resistant roller to replace the original roller. Since the wear resistance of the wear-resistant roller is better than that of the original roller, the wear of the roller during the rolling process can be reduced. In order to ensure the matching of the wear-resistant roller, it is necessary to adjust the parameters of the wear-resistant roller. In the present invention, the standard parameter range of the wear-resistant roller is first preset, and then the actual parameter value of the wear-resistant roller is obtained. If the actual parameter value of the wear-resistant roller exceeds the standard parameter range, the actual parameter of the wear-resistant roller is adjusted. If the actual parameter of the adjusted wear-resistant roller still exceeds the standard parameter range, the above steps are repeated until the actual parameter value of the wear-resistant roller is within the standard parameter range, and the debugging of the wear-resistant roller is completed.

[0079] In the present invention, the wear-resistant roll may be, but not limited to, a high-speed steel roll (HSS); the original roll may be, but not limited to, a high-nickel-chromium infinitely chilled cast iron roll (ICDP).

[0080] In an optional embodiment of the present invention, Figure 3As shown, the standard parameter range in step S1 includes: step S1': after the wear-resistant roller rolls the steel strip for a preset time or a preset length, obtaining the temperature range of the wear-resistant roller; step S2: obtaining the actual parameter value of the wear-resistant roller includes: step S2': after the wear-resistant roller rolls the steel strip for a preset time or a preset length, obtaining the actual temperature value of the wear-resistant roller. The specific temperature range of the temperature range of the wear-resistant roller can be set and adjusted by the rolling time of the steel strip or the length of the rolled steel strip. For example: if the maximum temperature of the wear-resistant roller is required to be maintained between 50°C and 60°C (preferably 55°C) after rolling the first 19 rolls of steel strip, it means that the parameters of the wear-resistant roller meet the requirements for rolling the corresponding steel strip; if it exceeds the preset temperature range (such as: the maximum temperature of the wear-resistant roller reaches 65°C), it means that the parameters of the wear-resistant roller cannot meet the requirements for rolling the corresponding steel strip, and it is necessary to adjust the width of the wear-resistant roller, the surface roughness and / or the setting position of the wear-resistant roller.

[0081] In an optional embodiment of the present invention, Figure 4As shown, the standard parameter range in step S1 also includes: step S1″: after the wear-resistant roller rolls the steel strip for a preset time or a preset length, obtaining the wear range of the wear-resistant roller; step S2: obtaining the actual parameter value of the wear-resistant roller includes: step S2″: after the wear-resistant roller rolls the steel strip for a preset time or a preset length, obtaining the actual wear of the wear-resistant roller. In addition to considering the temperature parameters of the wear-resistant roller, it is also necessary to consider the wear of the wear-resistant roller after rolling the steel strip for a preset time or a preset length. Only when the wear of the wear-resistant roller after rolling the steel strip for a preset time or a preset length is within the preset wear range, it is determined that the wear-resistant roller has good wear resistance and meets the rolling requirements for the steel strip. The specific wear range of the wear range of the wear-resistant roller can be set and adjusted by the rolling time of the steel strip or the length of the rolled steel strip. For example: after the wear-resistant roller rolls the first 19 rolls of steel strip, the maximum wear of the wear-resistant roller is required to be in the range of 0.05mm to 0.08mm (preferably 0.06mm), which means that the parameters of the wear-resistant roller meet the requirements for rolling the corresponding steel strip; if it exceeds the preset wear range (such as: the maximum wear of the wear-resistant roller reaches 0.2mm), it means that the wear of the wear-resistant roller is too large, and if the roller is not replaced, the requirements for rolling the corresponding steel strip cannot be met, thereby increasing the cost. Therefore, it is necessary to adjust the width, surface roughness and / or setting position of the wear-resistant roller, so that after the wear-resistant roller rolls the steel strip for a preset time or the wear-resistant roller rolls a preset length of steel strip, the actual temperature value and actual wear of the wear-resistant roller are respectively within the preset temperature range and wear range, thereby reducing roller wear and improving the uneven wear of the contact part between the roller and the edge of the steel strip.

[0082] Further, such as Figure 5 As shown, obtaining the actual wear amount of the wear-resistant roller in step S2" includes:

[0083] Step S201": Multiple detection points are selected on the surface of the wear-resistant roller at intervals and evenly along the width direction of the wear-resistant roller; wherein, the smaller the distance between two consecutive detection points (i.e., the greater the density of detection points on the wear-resistant roller), the higher the detection accuracy.

[0084] Step S202": drawing a wear morphology diagram of the wear-resistant roller based on the multiple detection points;

[0085] Step S203": Figure 6As shown, the wear morphology diagram is placed in a preset coordinate system (wherein the horizontal coordinate of the coordinate system is the width of the wear-resistant roller, and the vertical coordinate of the coordinate system is the thickness of the wear-resistant roller) (of course, each detection point can also be directly drawn in the coordinate system, and then each detection point is connected in sequence to form a wear morphology curve) to obtain the actual wear amount of the wear-resistant roller.

[0086] In an optional embodiment of the present invention, after step S2, the method further includes placing the steel strip in a horizontal direction, such as Figure 8 As shown, the thickness H of the middle position of the steel strip is obtained in the width direction of the steel strip. c And the thickness H of the steel strip at the two opposite side edges w and H d The three-point difference formula is used to verify the actual parameters of the wear-resistant roller after adjustment. The three-point difference formula is:

[0087] H=H c -(H w +H d ) / 2;

[0088] Among them, H is the tolerance of the steel strip; H c H is the thickness of the middle position of the steel strip in the width direction of the steel strip; w and H d They are respectively the thicknesses at the two opposite side edges of the steel strip in the width direction of the steel strip.

[0089] The three-point difference of the steel strip after rolling can be obtained through the three-point difference formula.

[0090] As shown in the following table, after 19 rolls of steel strips were rolled using the debugged wear-resistant rollers of the present invention and the original rollers, the three-point differences of the steel strips rolled by the wear-resistant rollers and the three-point differences of the steel strips rolled by the original rollers were obtained. It can be seen that after the wear-resistant rollers are debugged using the method of the present invention, the problem of large three-point differences after continuous rolling of the steel strips is effectively solved, thereby ensuring the rolling effect of the rollers on the steel strips, and being able to extend the service life of the rollers and reduce production costs.

[0091]

[0092] like Figure 6 、 Figure 7 As shown, after rolling, the maximum wear of the original roller in the width direction can reach 0.2 mm, while when rolling is performed using the wear-resistant roller of the present application, the maximum wear in the width direction after rolling is 0.06 mm. It can be seen that the use of wear-resistant rollers can effectively improve the wear resistance of the rollers and reduce the wear of the rollers during rolling.

[0093] In an optional embodiment of the present invention, after replacing the original rollers with wear-resistant rollers, the number of times the wear-resistant rollers roll the steel strips can be preset according to the actual different rolling accuracy requirements for the steel strips, thereby avoiding excessive wear on the wear-resistant rollers caused by rolling too many steel strips, and further preventing the three-point difference of the steel strip from being too large.

[0094] The characteristics and advantages of the roller debugging method of the present invention are:

[0095] The roller debugging method uses a wear-resistant roller to replace the original roller to improve the wear resistance of the roller and effectively reduce the wear of the roller during the rolling process. In order to ensure the matching of the wear-resistant roller, the standard parameter range of the wear-resistant roller is first preset in the present invention, and then the actual parameter value of the wear-resistant roller is obtained. If the actual parameter value of the wear-resistant roller exceeds the standard parameter range, the actual parameter of the wear-resistant roller is adjusted. If the actual parameter of the adjusted wear-resistant roller still exceeds the standard parameter range, until the actual parameter value of the wear-resistant roller is obtained within the standard parameter range, the debugging of the wear-resistant roller is completed, which ensures the adaptability of the wear-resistant roller while effectively improving the wear resistance of the wear-resistant roller, effectively reducing the three-point difference of the steel strip after rolling, and improving the rolling effect of the steel strip.

[0101] The comparison and judgment unit 30 is used to adjust the actual parameters of the wear-resistant roller if the actual parameter value exceeds the standard parameter range;

[0102] The parameter adjustment unit 40 is used to repeat the above steps until the actual parameter value obtained is within the standard parameter range.

[0103] In an optional embodiment of the present invention, Figure 10 As shown, the parameter preset unit 10 includes:

[0104] The first parameter acquisition module 1001 is used to obtain the parameter value of the original roller; wherein the parameter value of the original roller can be directly obtained by detecting the original roller, such as: the temperature value that the original roller can reach after rolling the steel strip for a preset time or the original roller rolls a preset length of steel strip, and / or the wear amount of the original roller, which can be obtained by collecting and recording data during the daily rolling process.

[0105] The parameter range determination module 1002 is configured to determine a standard parameter range for the wear-resistant roller based on the parameter values ​​of the original roller. This range includes the temperature range that the original roller can reach after rolling the steel strip for a preset time or a preset length, and / or the wear range of the original roller. Within this range, the wear-resistant roller is considered to meet the parameter standards and can meet the rolling requirements for the steel strip. It should be noted that the standard parameter range for the wear-resistant roller can be set and adjusted according to different rolling requirements for the steel strip, so long as the rolling requirements are met.

[0106] In an optional embodiment of the present invention, Figure 11 As shown, the parameter acquisition unit 20 includes:

[0107] The detection point acquisition module 2001 is used to select multiple detection points on the surface of the wear-resistant roller along its width direction; wherein, the smaller the distance between two consecutive detection points (i.e., the greater the density of detection points on the wear-resistant roller), the higher the detection accuracy.

[0108] A graph generating module 2002 is used to draw a wear morphology graph of the wear-resistant roller based on a plurality of detection points;

[0109] The second parameter acquisition module 2003 is used to place the wear morphology diagram in a preset coordinate system (wherein the horizontal coordinate of the coordinate system is the width of the wear-resistant roller, and the vertical coordinate of the coordinate system is the thickness of the wear-resistant roller) (of course, each detection point can also be directly drawn in the coordinate system, and then each detection point is connected in sequence to form a wear morphology curve) to obtain the actual wear amount of the wear-resistant roller.
